Had to do one in for a neighbor today who had it in a live trap.
Before I go further: we are in the suburbs, it has been the suburbs for over 60 years, none of the neighbors want them setting up shop in their yards, they have done serious damage to one of the houses in the neighborhood, and letting them live is simply not an option, so I don't want to hear it.
My neighbor is using live traps on them. This is primarily because her husband doesn't want to know they're getting offed. So we periodically have live groundhogs in traps that we need to dispose of discreetly.
Today I did what I've done for rabbits I was about to eat - 5lb sledge to the head. But groundhogs are apparently a lot tougher than rabbits and he took his sweet time dying. We also had to swing at it in the cage repeatedly to get it disabled so I could get a hold of its neck without losing a finger.
I don't exactly like doing or watching that, so I'm wondering if anyone knows a quicker way.
Firearms are out. Too populated, too likely we'll get visited. Suppressors are legal in VA with class 3 tax and paperwork, but if I end up having to deal with getting a can just so they don't have to suffer... well, congratulations federal government, now you're making animals suffer.
Be nice if we could get ahold of whatever animal control uses... watched them put down a racoon down the road with something in a needle a couple years ago and it took all of 5 seconds.
